Can you self-study or take a vocational program to learn a GDS?
Breaking into a new field, I expect it's common to work in an office, initially, to build skills and experience before being granted WFH opportunities (unless everyone in that role works from home, like some phone-based jobs). If you're really eager to make the switch, be open to working on site for a year or two (you're not moving to Portland immediately, nor having a baby immediately, so you have time to work your way into a flexible position).
